2)Javascript question - Is there any way of forcing the larger images we
use for the more info page into thumbnails, or do I have to resize all
the images individually?
Changing the HTML size tags can affect how an image displays onscreen,
but does nothing to change the image size. So if you have a JPG that's
50k at its normal size and you change the tags so it displays at 1/4 of
the size for a thumbnail, the browser still has to download 50k of image
and then crunch the numbers on-the-fly to display the image. No big
problem if there is only one image on the page, but if you have pages
with 75 thumbnails, each one requiring a 50k download and
post-processing, you're going to have a very slow-loading page. So yes,
you should have individually sized thumbnails.
That being said, there are a couple of solutions.
There are back-end programs that run on the server (GIMP being one of
them) and perform the conversions for you. These have their uses, but
you don't have a lot of control over the sharpness, colour balance, etc.
of the results.
My suggested solution is that you can just write an Action in Photoshop.
We have lots of images for our products and all of them need to be in
three sizes. We have an Action in Photoshop that basically lets us just
process a whole folder of images at a time. Quick, easy, painless.
Almost drag-n-drop, in fact. And Photoshop gives you complete control
over sharpness, colour palette, format, etc. So we end up with large
images for our More Info pages and small images for our catalogue pages.
